Some say, don't you exaggerate a litlle with emphasizing
the Cosmic Womb all the time. Well, apart from the Kala's the inside of the main temple
can be considered a symbolic Womb as well. Just like the crypts in Christian churches.....

Two Makara's at the entrance, Kala is absent

Inside the "Womb" to find a most sacred
(Tantric) object will not be a surprise anymore

The "classical" explanation is that Phallus and
Yoni symbolize the God Shiva and his lover Shakti. Originally, it is more like the Cosmic
Mother (Yoni) and Her Son/Lover Shiva (Phallus)
